Is it normal to be much more comfortable around the opposite sex?
I'm a girl in my mid 20's and have noticed that I've been much more comfortable around guys than girls for years, probably since I was a pre-teen or teenager. I still get along with and like other girls too, but I feel much more tense around them.
I also tend to be less comfortable around people in my age range than older people, and am comfortable with both men and women who are middle aged or older, for some reason.
I was bullied a lot as an adolescent mostly by girls I went to school with, so I'm not sure of that has anything to do with it. I have a few female friends I'm close with, but I tend to be able to really relax around guys and click with their personalities better.
